Answer to: Climate Sensor on Dash not "clicking"/AC blows HOTHello, Thank you for the replies. Having been guided on another forum to first look at the mono valve, I was able to find a Bosch mono valve on Ebay and I installed it tonight. I went for a cruise and (for now), I'm happy to report that it's blowing cold again. When I removed the old mono valve, I could not see anything obviously wrong with it, but I replaced it anyway. I don't know for certain if it needed a new mono valve, or if just the action of pulling the electrical connector off and on caused it to work again, but so far, I'm hopeful it working properly again. The true test will come tomorrow, during the heat of the day when I drive to work. Fingers crossed. Thanks again for the guidance, Brook
